This shouldn't need to be done with newer LIDARs, but included here in case. Leica suggests checking for torsion errors if there seem to be problems in the boresight calibration and reporting to them if found.

Classification is the process of labelling the points in the point cloud by type. Ground classification specifically refers to labelling points that're considered to be part of the ground(!) This is a required step for the automatic boresight procedure.

* remove very low, noisy points from consideration first

17

* e.g. remove groups of up to 3 points > 1m below neighbours (iterate a time or two so it settles)
